生存或发展：农民工工作匹配机制识别

采用联立方程法和Acemoglu识别法分别对农民工工作匹配决策机制加以识别,联立方程法检验结果表明收入正向且显著性影响工作任期,而福利虽正向影响并通过收入渠道间接影响工作任期但效果并不显著。Acemoglu识别法检验结果进一步支持了联立方程法检验结论,即农民工工作匹配决策机制为生存导向型,还未上升到发展层面,同时福利待遇已成为农民工稳定就业的重要考量因素。     

Use of Spacings in the Estimation of Common Scale Parameter of Several Distributions

In this article, we consider the problem of best linear unbiased estimation and best linear invariant estimation of the common scale parameter of several distributions using spacing of the pooled sample of all observations of individual samples. We derived conditions for the non negativity of the scale estimator obtained by the above methods. Further, we obtained necessary and sufficient conditions for the derived estimators to be constant multiples of the pooled sample range.     

Use of Quasi-Ranges in the Estimation of Scale Parameter of a Symmetric Distribution

In this article, we consider the problem of best linear unbiased estimation and best linear invariant estimation of the scale parameter of a symmetric distribution using quasi-ranges is considered. We also prove a sufficient condition for the non negativity of the scale estimator obtained by the above method. Further, we obtain necessary and sufficient conditions for the derived estimators to be constant multiple of the sample range.     

Bayesian inference with misspecified models

This article reviews Bayesian inference from the perspective that the designated model is misspecified. This misspecification has implications in interpretation of objects, such as the prior distribution, which has been the cause of recent questioning of the appropriateness of Bayesian inference in this scenario. The main focus of this article is to establish the suitability of applying the Bayes update to a misspecified model, and relies on representation theorems for sequences of symmetric distributions; the identification of parameter values of interest; and the construction of sequences of distributions which act as the guesses as to where the next observation is coming from. A conclusion is that a clear identification of the fundamental starting point for the Bayesian is described.     

Elsevier science digital libraries symposium

Abstract

This article discusses the growing need for tools or systems that will provide more effective management of and improved user access for journal collections, especially for e-journals. The author briefly describes initial efforts at the local library level to develop management systems and mentions the rise of vendor-supplied solutions, which have become very popular. In spite of the current popularity of vendor-based solutions, the author argues that there is still a niche for locally developed journal management systems. One such system, developed at the author's home institution, Taylor University, is featured as a case study.     

Do greater amounts of FDI cause higher pollution levels? Evidence from OECD countries

Using an ARDL model for a panel of 15 OECD countries, this work analyses the impact that FDI, both jointly and by sector, has on CO₂ emissions. The findings reveal that these countries are yielding to the pressure on the trade sector. Unexpectedly, gross fixed capital formation shrink pollution, excluding in the mining sector. With findings supporting the Pollution Haven Hypothesis, policymakers must pay attention to FDI inflows, ensuring that FDI place high importance on the transfer of green technologies to improve the efficiency. These goals could be achieved through an increase in the stringency of environmental laws within the host countries, especially the ones related to FDI.     

Gender gaps in STEM in Japanese academia: The impact of research productivity,outside offers,and home life on pay

To understand differences in labor market outcomes between genders, economists must examine a complex array of potentially significant factors, such as institutional context, productivity differences, child-bearing and home production, and bargaining behavior. Many of these factors are not well captured by standard data sources. We use a new survey of academics in Japan to better understand the sources of gender pay differences. We find a 6% pay gap which persists when we control for research productivity, despite an institutional context shaped by explicit salary tables. We do not find a motherhood wage penalty, and the gender salary we document is not affected by differences in outside job offers.     

Job satisfaction and mental health of temporary agency workers in Europe: a systematic review and research agenda

ABSTRACT

The current systematic literature review aimed to analyse the associations between temporary agency work (TAW), job satisfaction, and mental health in Europe, as well as to outline a future research agenda. Twenty-eight scientific articles were identified by searching different data bases (i.e. PSYNDEX, PsycINFO, PubMed, and Web of Science) for the time span from January 2000 to December 2016. Our review reveals first that TAW is not consistently negatively related to job satisfaction. However, job insecurity and working conditions are important mediators in the relation of TAW and lowered job satisfaction. Second, TAW is not consistently related to all investigated types of mental health impairments. However, when focusing on specific outcomes and comparing temporary agency workers to permanent employees, we still find consistent evidence regarding higher levels of depression and fatigue among temporary agency workers. Inconsistent associations between TAW, job satisfaction and mental health can partly be attributed to unfavourable methodological aspects of the included primary studies. To address these aspects, future research should consider applying a standard measurement of TAW, including a minimum of meaningful confounding variables, improving the operationalisation of outcome variables and the study design.     

Call centres and job satisfaction in Italy: employment conditions and socio-biographical patterns

ABSTRACT

The article examines job satisfaction in 21 Italian call centres. The results of research carried out on 1715 handlers indicate how dissatisfaction prevails among call centre representatives (CCRs) and how it is influenced by aspects related to some organisational characteristics (service delivered, size and organisational typology), on one side, and to different aspects of working conditions (contract, wage and tenure) and participants’ biographical and working profiles of CCRs (gender, age, educational attainment), on the others. However, the most interesting finding emerges by distinguishing different dimensions of job satisfaction (extrinsic and intrinsic-relational). In particular, the relationship between type of contract and job satisfaction is rather interesting. For non-permanent workers, in fact, the probability of being dissatisfied is decidedly greater if we consider the extrinsic dimension of job satisfaction. Instead, when the intrinsic-relational dimension is taking into account, atypical workers are no more dissatisfied than the permanent ones. Job insecurity and limited perspectives in terms of work alternatives, safeguards and rewards, seem to be the source of greatest dissatisfaction for Italian CCRs. This certainly does not surprise considering the Italian development model and its dualistic labour market, highly segmented between insiders and outsiders.
